Data from: Body condition influences ontogeny of foraging behavior in juvenile southern elephant seals
1. Ontogeny of diving and foraging behaviour in marine top predators is poorly understood despite its importance in population recruitment. This lack of knowledge is partly due to the difficulties of monitoring juveniles in the wild, which is linked to high mortality early in life. 2. Pinnipeds are good models for studying the development of foraging behaviours because juveniles are large enough to robustly carry tracking devices for many months. Moreover, parental assistance is absent after a juvenile departs for its first foraging trip, minimising confounding effects of parental input on the development of foraging skills. 3. In this study, we tracked 20 newly-weaned juvenile southern elephant seals from Kerguelen Islands for up to 338 days during their first trip at sea following weaning. We used a new generation of satellite relay tags, which allow for the transmission of dive, accelerometer and location data. We also monitored, at the same time, nine adult females from the colony during their post-breeding trips, in order to compare diving and foraging behaviours. 4. Juveniles showed a gradual improvement through time in their foraging skills. Like adults females, they remarkably adjusted their swimming effort according to temporal changes in buoyancy (i.e. a proxy of their body condition). They also did not appear to exceed their aerobic physiological diving limits, although dives were constrained by their smaller size compared to adults. Changes in buoyancy appeared to also influence their decision to either keep foraging or return to land, alongside the duration of their haul outs and choice of foraging habitat (oceanic vs plateau). 5. Further studies are thus needed to better understand how patterns in juveniles survival, and therefore elephant seal populations, might be affected by their changes in foraging skills and changes in their environmental conditions.
Figure 1 in A juvenile skull of Dysalotosaurus lettowvorbecki (Ornithischia: Iguanodontia), and implications for cranial ontogeny, phylogeny, and taxonomy in ornithopod dinosaurs
Figure 1. Reconstruction and comparison of the skull BSPG AS I 834 with the reconstruction of an older individual (modified from Janensch, 1955). The reconstruction of the juvenile skull was carried out by the combination of the frontoparietal plate, the left postorbital, the left squamosal, a combination of the left and the head of the right quadrate, the left jugal, the braincase, the right maxilla, the left laterodorsal maxillary process, and finally the right lower jaw with the left articular. Dark grey illustrates the skull openings, light grey illustrates the inner views of, e.g. the maxilla or the frontal, and the greyish pattern on the lower jaw and the braincase illustrates sediment. A, dorsal view of the skull reconstructed by Janensch (1955). B, left lateral view of the skull reconstructed by Janensch (1955). C, dorsal view of the reconstruction of BSPG AS I 834. For the unlabelled elements see the corresponding elements in (A). D, left lateral view of the reconstruction of BSPG AS I 834. For the unlabelled elements see the corresponding elements in (B). Note, for example, the difference of the mandibular articulation between (B) and (D). Furthermore, Janensch (1955) indicated the unknown quadratojugal in (B). This is omitted here. See Material and methods for a list of the abbreviations. Scale bars: 1 cm.

Figure 2. Stereo pairs of the skull BSPG AS I 834 and explanatory sketches. The sketches are relatively enlarged for better resolution. Dark grey illustrates sediment, light grey illustrates inner views of, e.g. the frontals or the dentaries, and hatched areas illustrate broken or corroded surfaces. The label affixes -r and -l stand for right and left of the respective element, where the distinction of each side is difficult to see. A, left lateral view. B, outline drawing of the left lateral view. C, outline drawing of the occipital view. D, occipital view. See Material and methods for a list of the abbreviations. Scale bars: 1 cm.
